METHOD OF MANUFACTURING A CHEMICAL MECHANICAL PLANARIZATION PAD

摘要

The present disclosure relates to a process for forming a chemical mechanical planarization pad. The process includes forming a chemical mechanical planarization pad including a polymer matrix and an embedded structure by heating the polymer matrix and the embedded structure at a first temperature T1 and a first pressure P1. The chemical mechanical planarization pad is then allowed to deform at a second temperature T2 and a second pressure P2. The chemical mechanical planarization pad is then compressed at given mold cavity thickness by applying heat at a third temperature T3, wherein T1> T2, P1>P2, T1≤T3.
